Description

end-to-end tests frequently modify the configuration before running a test; to set state backends, # of task slots, reporters, etc.

Currently it is the responsibility of the test to create a backup of the config before doing any modifications, which is then restored by the runner after the test.

Instead we can have the test runner always create a backup before running the test.
